(14) FIG. 1 shows a roadway joint device 1 of a bridge 2, in which a bridge superstructure is rigidly connected with an abutment and extends to a bridge end section 2.1. The bridge end section 2.1 herein forms, for example, an edge substantially transversal to the longitudinal direction of the roadway. The roadway joint device 1 further includes a retaining device 3, several joint elements 4 as well as rods 5, which are arranged through the joint elements 4 and connect the joint elements 4 with each other. Each joint element 4 in the embodiment illustrated herein in FIG. 1 has a substantially cuboid form with a longitudinal axis 4.1 as well as a quadrangular, e.g., square or rectangular, cross-section 4.2. The joint elements 4 in FIG. 1 are connected with the bridge 2, as well as with the retaining device 3, by way of the rods 5. For this purpose, a first rod end 5.1. of each rod 5 is anchored in the bridge 2 using an anchoring 6 of the rod 5. The respective opposite other rod end 5.2 of the rod 5 is attached in the retaining device 3 using an anchoring 7 of the rod 5. The rods 5 in this embodiment of the invention have to be composed of a corrosion-resistant material. Suitable materials for such rods 5 may be, e.g., stranded litzes made from rust-resistant steel, rods made from plastic materials or wire made of fibre composite materials. The bridge anchorings 6 or the retaining anchorings 7, respectively, of the rods 5 may also configured as compound anchorings. Alternatively, also anchoring systems known from reinforced concrete constructions may also be used for anchoring 6, 7 the rod ends 5.1. or 5.2, respectively.

(15) There is further visible in FIG. 1 a sliding surface 8 already prepared, which is arranged in an area between the retaining device 3 and the bridge end section 2.1 of the bridge 2. According to FIG. 1 the approximately cuboid joint elements 4, which are herein made from concrete, are mounted on the sliding surface 8 and arranged between the retaining device 3 and the bridge 2. The sliding surface 8 may be configured, e.g., as a bituminous layer on a load-bearing layer 13.

(16) There is visible in FIG. 2 that the cuboid joint elements 4 in the plan view are arranged substantially parallel to the end of the bridge 2. In the embodiment illustrated there are used, for example, seven approximately cuboid joint elements 4 each having longitudinal axes 4.1. extending substantially parallel thereto. Five rods 5 are intended for the uniform connection and load distribution, respectively, across the entire width of the roadway.

(17) For the function of an inventive roadway joint device 1 a direct connection of the rod 5 with the cuboid joint element 4 that is illustrated in FIG. 3, is of importance. This direct or rigid, respectively, connection between respectively the rods 5 and each cuboid joint elements 4 is established, for example, most easily by concrete-casting the rods 5 into the cuboid joint elements 4. In this way, compound tensions from the rods 5 may be transferred to the joint elements 4 attached thereto in a uniformized way, and in this way longitudinal expansions of the bridge 2 may be compensated for.

(18) An alternative embodiment of the connection between a rod 5 and a cuboid joint element 4 is illustrated in FIG. 4. If the rod 5 is made of a not corrosions-resistant material, then there is required in addition as a protection against corrosion an encapsulation of the rod 5 in a cladding tube 9, wherein the cladding tube 9 is made of a corrosion-resistant material. Suitable materials for rods 5 in this embodiment having a cladding tube 9 protected against corrosion are, for example, ropes or stranded litzes made of metallic materials. The approximately cuboid joint element 4 is therein in a respectively direct contact with a cladding tube 9, within which the rod 5 is arranged. A force-fit connection between the cladding tube 9 and the rod 5 situated therein is produced by filling with grouting mortar 10. Upon hardening the grouting mortar 10 will be able to transfer compound tensions between the cladding tube 9 and the rod 5. Hence, also in this embodiment the transfer of longitudinal expansions of the bridge 2 to the rods 5 and from these further to the joint elements 4 is ensured. The cladding tube 9 is attached with the two cladding tube ends 9.1 or 9.2, respectively, thereof also in the bridge 2 or in the retaining device 3, respectively, in the area of the anchorings 6, 7.

(19) FIG. 5 shows in a sectional view along the line V-V from FIG. 2 the arrangement of the cuboid joint elements 4 on the sliding surface 8 in detail. Between the two neighbouring cuboid joint elements 4 there is present respectively one joint gap 11 having a gap width 11.1, in which the rod 5 is not embedded in concrete. Into the exposed joint gap 11 surface water, thawing agents and dirt may enter, which is why the embodiment of the rod 5 is required to be made of a corrosion-resistant material in order to ensure a permanent structure.

(20) Contractions of the bridge 2, which are, for example, conditioned by a temperature decrease, will lead to an expansion of the distance between the retaining device 3 and the bridge end section 2.1 and, hence, to an expansion of the rods 5. Due to the expansion of the rods 5 there is caused an opening of the joint gaps 11 or an enlargement of the individual gap widths, 11.1, respectively, as the individual joint elements 4 are attached to the rods 5 in a direct and stationary way. The longitudinal deformation of the bridge 2 is distributed in regard to the stationary retaining devices 3 or the bridge anchorages 7 of the several rods 5, respectively, approximately uniformly by the inventive roadway joint device 1 across the, in this example eight, longitudinal gaps 11 formed, as is illustrated in FIG. 2. For example, in the case of a longitudinal deformation of the bridge 2 by in total 80 mm, the longitudinal deformations acting in total are distributed onto the number of the joint gaps 11 in a uniform way. In the case of eight joint gaps 11, the deformation of every individual joint gap 11.1 in the case of a total deformation of 80 mm will thus be respectively only 10 mm, which may be handled in a comparatively easy way.

(21) The uniformized changes of the gap widths 11.1 are only possible if tensile and pressure forces are being developed in the rods 5. These tensile or pressure forces in the rods 5 will lead to the corresponding longitudinal changes of the rods 5. By the stationary attachment of the individual joint elements 4 along the rods 5, in the case of longitudinal deformations of the bridge 2 the joint elements 4 are appropriately moved back and forth on the sliding surface 8 between the retaining device 3 and the bridge end section 2.1, thus compensating for the entire deformation of the roadway joint device 1 and distributing or uniformizing, respectively, it onto several individual joint gaps 11 with variable joint widths 11.1.

(22) Expansions of the bridge 2, for example as a consequence of a temperature increase, will lead to a reduction of the gap widths 11.1 of the joint gaps 11. The number of the joint gaps 11 as well as the gap widths 11.1 are to be appropriately configured when planning the roadway joint device 1. If the gap width 11.1 becomes smaller than when originally projected when producing the roadway joint device 1, then pressure tensions will be developed in the rods 5 or also in the cladding tubes 9 according to embodiment, respectively, as well as in the grouting mortar 10. In the configuration of the roadway joint device 1, hence, it is to be taken into account whether the pressure tensions may be absorbed by the rods, or whether a projected stability failure will occur, which might lead to an earlier closing of the joint gaps 11 adjacent to the bridge 2. In an embodiment with cladding tubes 9 and grouting mortar 10 there is further to be taken into account that the extensional rigidity of the roadway joint device 1 must not become too large in the case of pressure stress in the rods 5.

(23) For the tensile forces developing, the behaviour of an inventive roadway joint device 1 may be compared with a rod made of reinforced concrete, in which cracks may be formed in the course of tensile stress. The longitudinal change of the rod made of reinforced concrete is approximately the sum of the increase in the crack widths. The concrete pieces between the cracks are exposed to a certain tensile stress due to compound tensions, which are conducted by the reinforcement rod into the concrete pieces, and thus have expansions. The extensional rigidity of the concrete pieces between the cracks, however, is many times higher than the extensional rigidity of the reinforcement rod, which is still present in the cracks.

(24) The forces developing in the rods 5 during a deformation of the bridge 2 have to be absorbed by the retaining device 3. If the retaining device 3 is arranged, for example, on an embankment, then it is appropriately difficult to configure, or it has be anchored in the embankment using so-called geogrids or similar anchoring means. If the bridge 2, for example, is erected adjacent to a tunnel, then the retaining device 3 may also be integrated in the bottom surface of the tunnel, thus being anchored in a stationary way.

(25) In the embodiment example illustrated herein there is present, upon completion of the bridge 2 with a drivable roadway 16 made from concrete and a roadway 16 made from concrete adjoining the roadway joint device 1, a continuous roadway surface made from concrete.

(26) The production of an inventive roadway joint device 1 is explained in the following by way of the schematic depictions FIG. 6 to FIG. 11.

(27) FIG. 6 shows an initial situation of a bridge 2 being mounted on the abutments 17 using bridge bearings 20. Laterally adjacent to the abutments 17 there has already been introduced a backfilling 18. Herein a so-called drag plate 19 resting on the backfilling 18 is rigidly connected with the abutment 17. On the drag plate 19 and on the backfilling 18 there is produced a load-bearing layer 13. Embedded in the load-bearing layer 13 is the retaining device 3. On the load-bearing layer 13 there is formed a sliding surface 8 between the retaining device 3 and the end of the bridge 2.

(28) According to FIG. 7 in the next step of the production method there are placed, e.g., trough-like prefabricated elements onto the sliding surface 8 so that there will remain deliberate joint gaps 11 each having gap widths 11.1 between the trough-like prefabricated elements 14. The prefabricated elements 14 herein are made from concrete and each have longitudinal axes 14.1. The prefabricated elements 14 herein are configured substantially trough-like having a recess 14.2 and placed onto the sliding surface 8 so that the recesses 14.2 are each situated at the upper surfaces thereof.

(29) In the following step, which is illustrated in FIG. 8, the rods 5 are installed between the retaining device 3 and the bridge 2. The rods 5 are guided substantially transversally through all trough-like prefabricated elements 14 and being anchored at respectively one rod end 5.1 thereof using bridge anchorings in the bridge 2 as well as at the opposite rod end 5.2 thereof using retaining anchorings 7 in the retaining device 3. At the ends of the trough-like prefabricated elements 14 there is attached a boarding.

(30) In the next step according to FIG. 9 there is introduced filling concrete 15 into the trough-like prefabricated elements 14. Before the introduction of the filling concrete 15, the positions, at which the rods 5 are guided through the trough-like prefabricated elements 14, are to be sealed respectively at the internal surfaces of the trough-like prefabricated elements 14 using an appropriate sealing 21. By the introduction of filling concrete 15 into the trough-like prefabricated elements 14 there will then be formed joint elements 4, which each are directly connected with the rod 5.

(31) Finally, according to FIG. 10 there is applied an asphalt cover layer 12. The asphalt cover layer 12 extends continuously on the load-bearing layer 13 of the embankment, on the roadway joint device 1 and on the bridge 2. The driving comfort is substantially improved by the formation of a roadway 16 having one plane 16.1, which is formed by the continuous asphalt cover layer 12, in comparison with conventional embodiments of roadway joint structures, in which the roadway in different sections is composed of respectively different materials with respectively different roadway characteristics.

(32) The material of the continuous asphalt cover layer 12 and the uniform changes of the gap widths 11.1 of the joint gaps 11, hence, are to be carefully coordinated. An enlargement of the joint gaps 11 is to be absorbed by appropriate expansions in the asphalt cover layer 12. In the case of an intact, crack-free asphalt cover layer 12 the surface water is discharged via the asphalt cover layer 12 to the edge of the roadway 16. If there is allowed a projected formation of cracks in the asphalt cover layer 12 in the area of the variable joint gaps 11, then the sliding surface 8 situated underneath is to be embodied as a sealing plane against surface water.

(33) FIG. 11 shows in a detailed view A according to FIG. 10 in an enlarged scale the approximately trough-like prefabricated elements 14, which have already been filled with filling concrete 15. Each rod 5 is therein in direct contact with the filling concrete 15 and connected therewith in a stationary way. Within the feedthroughs through the trough-like prefabricated elements 14 as well as in the projected joint gaps 11 the rod 5 is freely movable, which will contribute to the desired appropriately large deformations of each rod 5 within its sections that are freely movable in the case of tensile or pressure stress. In this way, there is ensured that the joint elements 4 will be moved back and forth on the sliding surface 8 without any delay in the case of longitudinal changes of the bridge 2 due to tensile or pressure stress. A jolt-like and delayed rupture of the joint gaps 11 together with a peak stress associated therewith of the continuous asphalt cover layer 12 thus will be prevented.

(34) If the roadway width of the bridge 2 becomes too large, then it may be advantageous to produce the trough-like prefabricated elements 14 each consisting of two or more individual trough-like prefabricated elements 14 and to connect these several prefabricated elements 14 each at the front sides or front surfaces 14.3, respectively, thereof lined-up in the direction of the longitudinal axis 14.1 on the sliding surface 8. By appropriate sealing measures in this case is to be ensured that no leaking of the filling concrete 15 can occur at the joint positions between lined-up prefabricated elements 14. In such an embodiment having front-side aligned prefabricated elements 14 it may be, e.g., advantageous to arrange a reinforcement within the trough-like prefabricated elements 14 in the area of the joint points. In this way, the individual lined-up and trough-like prefabricated elements 14 are connected into a continuous, approximately cuboid joint element 4 via the reinforcement and the filling concrete 15.

(35) By way of the illustrations FIG. 6 to FIG. 11 there was shown as an example the production of two inventive roadway joint devices 1 each having seven lined-up cuboid joint elements 4 adjacent to the two bridge end sections 2.1 of a bridge 2. The number of the joint elements 4 per roadway joint device 1 is dependent for real-life applications on the deformations to be absorbed. The number of the cuboid joint elements 4 installed in the roadway joint device 1 may, hence, range between 1 and 100. The joint elements 4 in the illustrations FIG. 7 to FIG. 11 have approximately the same dimensions. It may be advantageous to produce the joint elements 4 having different dimensions and to configure the joint element 4 adjoining the bridge 2 with an enlarged width, for example. Correspondingly, an inventive roadway joint device 1 may also be used in structural engineering as well as in civil engineering if a drivable or walkable structure surface is to be produced with simultaneous absorption of different deformations between two parts of a structure. These embodiments, however, are not explicitly depicted in the illustrations, but are nevertheless covered by the invention.
